I did some searching, but couldn't find anything all encompassing.
Has anyone bought/installed a UMI full kit (any "stage") for '68-'72 A-body that could share their thoughts and likes/dislikes? Or any other vendors that would get me to a lowered, great handling A-body that all works well together? Spindle choice, stock or other? Parts that don't come with the kit, what was used stock or other?

I am planning this build slowly while the 455 is out getting worked.
Thanks all,

 

I have UMI upper and lowers in the rear with an oversized sway bar and its very nice BMR upper and lowers up front with oversized sway, seems to all work well with each other.

 

I have UMI fixed rear upper and lower tubular control arms and their sway bar. Very happy with the product.

 

Last summer I installed the UMI Stage 2 kit on my ‘72 Convertible with a 350. The kit went in with no problems, everything lined up perfectly. The kit included upper and lower control arms (front and rear), sway bars (front and rear), springs and shocks(Bilstein). A couple of thoughts……I bought the 1 inch lowering kit, there was no difference in ride height, probably due to replacing 50 year old springs. The kit came with taller than OEM ball joints. Had to use quite a few shims to align the front end. I love the ride and handling. Even my wife noticed the difference.

 

I purchased UMI Performance - very happy, quality products.
Winter Project - '71 CS Suspension

 

Can't comment on their springs or shock offerings, but I'm really happy with all of the hard links - front upper and lower a-arms, rear upper and lower control arms, and front/rear sway bars. High quality stuff and quick responses from tech support when needed.

 

I’m thinking Stage 5…🥳
